Subject: [PATCH] fix: use stat -L to follow symlinks when checking checkpoint
 file size

HuggingFace cache stores files as symlinks to blobs, so stat without -L
was returning the symlink size (76 bytes) instead of actual file size (6.5GB).
This caused the >500MB check to fail and skip linking checkpoint files.
